Fuel differences

[Gatecrasher]

Hey guys ever since I have had the car I've been using shell v power and was fairly whatever about it, I tried the Safeway caltex premium and that was just nasty - car ran rougher and mileage was horrible. So I went back to v power just cos I knew it was ok. Someone at work said that BP ultimate was the best so I gave it a crack and I'm surprised at the difference compared to v power. The car seems to run smoother and glide easier when I jump off the accelerator, the gearstick also feels nicer hardly any vibration at all.

Have u guys experienced differences with the petrol you use?

At one stage I filled up with Caltex Vortex 98 and that tank lasted a while and car seemed to run pretty well off it. Just my 2cents

i use whatever 98 octane aslong as its from a somewhat reputable source (usually shell, mobil, bp very rarely caltex).

used vortex98 in all of my cars, none of them have had an issue, and mileage has been great :) (currently getting 650 in the astra on a 50L tank, and 550 in the GTi on a 45L tank... 550 conservatively lol)

edit: dont forget, its also down to the oil you use aswell... but thats for another topic ;)

I normally run v power on mine aswell till one time there was no shell open and I was running low so I had to stop at a bp and tried the ultimate and yeah I agree the car seems to be smoother to drive..

I thought it was just in my head so it's good that someone else felt it too..

But one thing I noticed though, I don't get very high milage.. Though that's probably coz I use the aircon often nowadays..

I use BP ultimate only because its right next to my house, otherwise im not bothered.

Like Hazrd has said its also to do with the oil you use.

I have a feeling they use mobil oils...however I could be wrong

I use BP Ultimate 98 90% of the time other wise the car seems to really like Mobil 98 but those petrol station a rare around these parts, and V-Max 98 car runs nicely on. Ill only use Caltex 98 if there is nothing else but only put like $15 to get me to another station, car just seems to run better on the others.

Mileage has a lot to do with the kind of driving you do. I've had over 700 out of my Astra (G), and that was just whatever the 7-11 down the road sells as their el-cheapo E10. That was mostly motorway trips though, and no stop-start traffic. I won't get that kind of mileage any more - the kids are back at school now, and that means there's far more people causing traffic jams at 8 in the morning, so I'm in queueing traffic at least 5 minutes each day now just trying to get onto the motorway. (They *really* need to fix that junction).

Oh, and as to petrol choice? The Astra gets whatever's going cheap when it needs some, hence my using the local 7-11, as they seem to be really competitive on price. The Vectra (2.6L V6) is more picky - wanting at least 95 octane. I used to run it almost exclusively on Freedom, but I've now switched to United - Freedom changed their supplier, and it really didn't like their new petrol. I suspect it wasn't quite the same octane ratings, as shortly afterwards, all the octane ratings disappeared off the Freedom pumps...

A lower viscosity oil, i.e 5w30 will aid fuel consumption.
